AUTOMATIC GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 697,429, dated April15, 1902.

Application filed November 26, 1900. Serial No. 37,796. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN F. APPLEBY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented' certain new and useful Improvements in AutomaticGrain-Binders; and I do hereby declare thefollowing to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to certain improvements in the gearing fordriving the packershaft of self-binding harvesters.

The object of my invention is to provide means by which the packers maybe allowed to come to rest while the bundle is being bound. Y

` This invention may be considered animprovement on the machine shown inPatent No. 552,503, granted to me January 7, 1896. In the said patentthe driving-shaft is so mounted that it is capable of being moved bodilyto carry the spur-gear mounted thereon out of mesh with the spur-gear onthe packer-shaft, and the needle is made to effect this movement of oneend of the packer-shaft by engaging a pivoted arm in which the bearingfor said end of the driving-shaft is carried. This necessitatesrevolving the driving-shaft in a direction opposite to that of thepackershaft. In my present invention I provide means for disengaging anintermediate pinion which meshes with a driving-pinion secured to thedriving-shaft from the spur-gear secured to the packer-shaft. By thismeans I am able to revolve. the driving-shaft in the same direction asthe packer shaft, as required by the majority of harvesters. Thisdisengagement is effected by means of a cam located on the needle, whichcomes in contact with an operating-arm, which is secured to a vibratingarm pivoted on the driving-shaft carrying the intermediate pinion.

I have shown in the accompanying drawings the ordinary bindingmechanisms. and the general type of gearing illustrated in theabove-mentioned patent and have applied my improvement thereto, showingonly such parts of a binding attachment as necessary to illustrate thegeneral features of my invention.

Figure l is an elevation. Fig. 2 is a detail view of the means I providefor causing the packers to intermit in their action, andFig. 3 is a planview.

Referring to the drawings, A is the main binder-frame, of the usual formof const-ruction; a, the needle-shaft; et', the knetter-driving shaft,and 0.2 the needle. These two shafts are connected by the usualcrank-wrist formed upon them and the pitman I3:

C is the driving-shaft, mounted in suitable bearing, c thedriving-sprocket, and c' a bevelpinion secured to said driving-shaft.

D is a shaft having bearings in the main frame of the binder and partsattached thereto, provided with a bevel-pinion CZ at its upper yend andbevel-gear d at its lower end. By'

means of the bevel-pinion and the bevel-gear last named the rotation ofthe driving-shaft is imparted to the knetter-driving shaft.

Upon the driving-shaft at c2 are the usual clutching devices. To theinnerend of the binder-frame is secured the yoke E, carrying thebearings e and e. In thesev bearings is mounted the packer-shaft e2 withits cranks. To said packer-shaft is secured the spur-gear e3. Near theinner end of the driving-shaft is secured a spur-pinion c3. Concentricwith the driving-shaft is pivoted the vibrating arm c4, carrying anintermediate pinion c5, which meshes with the driving-pinion c3 and isadapted to mesh intermittently with the spurgear e3, secured to thepacker-shaft.J

Said vibrating arm c4 is secured to a sleeve cs, the other end of whichisprovided with an operating-arm c6, which is adapted to engage a cama3, located upon the needle.

When sufficient grain has been received into the binding mechanism toform a bundle and the mechanism been setin motion through the agency ofthe ordinary tripping devices, the needle a2 rises and moves forward.The cam a3, located thereon, engages the operating-arm c6 and raises itthereby, rocking the vibrating arm c4, carrying the intermediate ,pinionc5 upon its pivot, thus disengaging the said intermediate pinion fromthe spur-gear e3 on the packer-shaft. By this disengagement the packersare allowed to remain at IOO rest while the bundle is being bound and tobe free in their movement as determined by the grain delivered upon thedeck back of the needle. Vhen now the bundle has been bound anddischarged and the needle a2 returns to its position of rest, the cam(t3 allows the operating-arm c of the vibrating arm c4 to drop down asthe needle recedes to or near the hub of the needle, thereby rocking thevibrating arm carrying the intermediate pinion c5 and engaging saidintermediate pinion again with the spur-gear e3, secured to thepacker-shaft, thus imparting the motion of the dri ring-shaft to thepacker-shaft, setting the packers again in operation. To make positivethe rocking of the Vibrating arm c4 upon its pivot, a spring e7 isprovided to react between said vibrating arm and the yoke E. Due to therelation of the driving-shaft and the packer-shaft to the axis of theintermediate pinion when the intermediate pinion begins to engage withthe spur-gear the force imparted by the driving-pinion operating againstthe resistance of the packers tends to make it engage more vigorouslywith the spur-gear, thus holding it firmly in mesh. To prevent the saidgears from meshing too closely together, they are provided Withpitchline shrouds, the peripheries of which roll together, forming anautomatic stop. By forming a stop in this manner any variation inmanufacture will not prevent the gears meshing together perfectly.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a grain-binder, the combination with the packer-shaft, of adrive-shaft mounted in fixed relation to and rotating in the samedirection as the packer-shaft, gears on said shafts, a swinging armpivoted coaxially with the drive-shaft and carrying an intermediate gearnormally meshing with both gears, a connection between the arm and amovable part of the binder to swing the arm so as to disconnect theintermediate gear from the packer-shaft gear when the needle rises, andmeans for swinging the arm so as to cause the intermediate gear to rollaround the driveshaft gear into mesh with the gear on the packer shaftwhen the needle falls, said packer-shaft gear and intermediate gearbeing provided with pitch-line shrouds to form stops to prevent themfrom being thrown too closely into mesh.

2. In a grain-binder, the combination with the packer-shaft, of adrive-shaft mounted in fixed relation to and rotating in the samedirection as the packer-shaft, gears on said shafts, a rocking sleeve onthe end of thc drive-shaft that projects beyond the gears, an arm on oneend of the sleeve carrying an intermediate gear meshing with thedriveshaft gear, a cam on the needle, and an arm projecting from theother end of the sleeve in the plane of movement of the cam.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOHN F. APPLEBY.
